What 90853 covers

A clinician leads a therapeutic session in which multiple patients work on behavioral health concerns through guided discussion, therapeutic exercises, and interaction with the group. Psychiatrists, psychologists, and other qualified mental health professionals may provide the service in settings such as an outpatient office or hospital outpatient department. The group session is distinct from a meeting limited to multiple families receiving treatment together.

Report 90853 for each patient receiving group treatment, supported by that patient’s record—not once for the group as a whole. Documentation should identify the group service, its therapeutic focus and interventions, and the patient’s attendance, participation, response, and connection to the treatment plan. Select this code for group psychotherapy, not for an individual psychotherapy session or family psychotherapy. CMS assigns work, practice-expense, and malpractice relative values; the practice-expense values differ between office and facility settings.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

90853 billing questions

How is 90853 different from individual psychotherapy?

90853 describes treatment delivered in a group setting. Use an individual psychotherapy code when the clinician treats the patient individually rather than as part of a group.

Is 90853 billed once for the group or for each patient?

Report the service for each patient who receives group treatment. Each patient’s own record must support attendance, participation, and medical necessity.

Does 90853 cover multiple-family group therapy?

No. Multiple-family group psychotherapy is represented by 90849; 90853 is for group psychotherapy that is not a multiple-family group.

What should the record include for 90853?

Document the group’s therapeutic focus and interventions, the patient’s attendance and participation, the patient’s response, and how the service relates to the treatment plan.

Does group size require a modifier?

Group size is not specified by 90853. Record the patient’s attendance and participation in the clinical note.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
